TOBACCO-SMOKING PIPE.

Application filed July 31,

This invention relates to improvem nts tobacco smoking pipes and has for. its obect to provide an improved construction of pipe having a tobacco chamber; a salivareceivmg chamber and a novel arrangement of passages and valve device between the two chambers and the mouthpiece whereby". to

prevent. saliva from draining from the mouthpiece into the tobacco chamber and ensuring the collection of such saliva in the saliva chamber. 7

A further object is to provide a novel construction and arrangement of chambers, passages and valve whereby the same are readily accessible for cleaning. I I With these, and other objectsin View, the invention is illustrated in the accompanying drawing, wherein,

Fig. 1 shows a longitudinal sectional detail through the bowl and stem and also shows the mouthpiece in side elevation.

Fig. 2 illustrates the bowl and a portion of the stem'in top view.

Fig. 3 shows the detached ferrule in side elevation.

Fig. 4 illustrates the detached. valve-plate and valve on an enlarged scale, and

Fig. 5 shows a sectional detail through the valve-plate and valve,the section being taken on the line 55 of Fig. 4:.

Referring to the drawing the numeral 6, designates the bowl of the pipe, 7 the stem thereof and 8 the mouthpiece.

The particular shapes of these elements may be varied at will and need not be those shown in the drawing.

The bowl 6 has a partition 9 which divides the same into an upper tobacco chamber 10 and a lower saliva-chamber 11. The saliva chamber 11 is closed by a detachable cap 12 which latter has a screw-threaded connection 13 with the bottom of the bowl as shown in Fig. 1 of the drawing. 7

From the tobacco chamber 10, there is a passage 1 1, which extends longitudinally through the stem 7 and in the end bf this passage I provide .a tube 15, having a slightly-curved end 16 as and for a purpose presently to be explained.

From the lower saliva chamber 11, I provide another passage 17 which also extends longitudinally through the stem and the rear end of this passage opens into a valveecham- 1926. Serial No. 126,202.

ber 18 which 1 form in the rear end of the stem between the two passagesl l and 17 A vent passage .19 extends down through the bowl-wall from the rim edge 20 and opens into the lower saliva-chamber 11,''

the lower end of said passage 19 preferably hav ng a tube 21 therein whose lower end 22 pro ects into the saliva-chamber and curves laterally also for a purpose that will pres-' ently be explained.

. The rear end of the stem 7 is circumferentiallyreduced so that a ferrule 23, may have one end fitted thereon and be flush on the eXterior'wit-h' the stem, and the rear face of the stem has a slight circular recess 24, so

as to receive a circular valve-plate 25. I

This valve-plate 25 as will be seen in Figs. land 5, is circular in form and has, a perforation 26, in its upper portion and has a fia -valve 27 which covers a lower erfora-' tion-28. The weight of this valve is suflicient. to keep it normally closed'over the valve-perforation 28.

,The particular construction of thisvalve plate and valve is not essential but it is esvalve be provided.

sential that some form of It will be noted by reference to Fig. 1, of the drawing that the perforation 26 in the valve-plate is so located that the tube 15, from passage 1 1, may project therethrough while the valve 27 and perforation 28 are so located as to be directly at the rear of the saliva-passage 17 The ferrule 23 is recessed at its forward end to fit over the reduced rear end of the stem and also has a circular recess 29 at its rear end which is internally screw-threaded so as to receive the screw-threaded nippleend 30 of the mouthpiece 8.

Between the recessed ends, the ferrule has a central reduced passage 31 and when the ferrule is in place on the stem, this central passage 31 receives the curved end 16 of the tube 15 which projects through the perforation 26 in' the valve-plate.

It will also be noted that when the ferrule is in place the wall in front of the central passage 31, will seat against the rear face of the valve-plate and hold the latter in place in the circular recess 24: at the rear of the stem;

When the smoker draws through the stem suction will be created in the tube 15 and passage 14 to draw the smoke from the chamber 10. This same suction will also tend to keep valve 27 closed so that there will be no suction from chamber 11, through passage 17.

Saliva that may flow through the stem will drip into the Ollilll'lbtlidl ofthe ferrule and will flow therefrom through alve-port 28 into the valve-chamber 18 and will run through passage 17 and collect in chamber 11. W

In casethe pipe tilted as when placed in the pocket out" the user, the tube-ends 1G and will prevent saliva that may have collected in either the chamber-31or the bowichamber 11, from passing into the tubes 15 or 21. a

The tube 21 andpassage 19 in thebowl wall serve as vents so as to facilitate the therein to form a tobacco chamhe' and a saliva chamber, said pipe having a stem with one passage extending therethrough from the tobacco chamber and another passage ex tending therethrough from the saliva cham her, a mouthpieceat the end of the stem and sage, and a valve interposed between the mouthpiece and the passage leading to the saliva chamber of the bowl.

3. A pipe having a bowl with a partition therein to form a tobacco chamber and a saliva chan'lber, the bowl also having a vent passage from the saliva chamber tothe ex tenor of the bowl, said vent passage being provided with a tube at the saliva chamber which pro ects into the latter, and a valve interposed between the mouthpiece and the passage leading to the saliva chamber otthe bowl,

A pipe having a bowl with apartition projecting from the tobacco chamber passage and extending through the said plate to the rear side thereof.

In testimony whereof l jaflix my signature.
